RE: Lung Biopsies
|From:||"Marshall Terry Dr, Consultant Histopathologist" |
I presume it is transbronchial biopsies that you are talking about. Best of luck. Having done these (not in great numbers) for 25 years, I can tell you that the value of these things is very limited. As I think you are suggesting, any alveolar tissue is collapsed, and I have always had difficulty in deciding if it is fibrosis or factitious collapse. Most seem to be bronchial wall and fibrous strands coming from it only.
Altogether, a frustrating exercise.
Just occasionally, one can recognise sarcoid.
I don't think there could be anyway to expand collapsed alveoli. The real problem with these biopsies is that they are just too ruddy small!
Many years ago, (not in relation to transbronchials) I read of a technique of putting lung in soda water, the idea being that as the gas came out of solution, it filled the alveoli.
Anyone tried this?

I was wondering what methods people were using for processing lung biopsies?
Are there any particular protocols which result in good histology and
structured i.e. where the alveoli have not collapsed?
